Streamlined approaches for confirming ASD case status would benefit these studies. We conducted a multi-site, cross-sectional criterion validity study in a convenience sample of 382 three-year olds scheduled for neurodevelopmental evaluation. ASD case classification as determined by three novel assessment instruments (the Early Video-guided Autism Screener E-VAS; the Autism Symptom Interview, ASI; the Screening Tool for Autism in Toddlers Expanded, STAT-E) each designed to be administered in less than 30 minutes by lay staff, was compared to ADOS scores and DSM-based diagnostic assessment from a qualified clinician. Sensitivity and specificity of each instrument alone and in combination were estimated. Alternative cutpoints were identified under different criteria and two-stage cross validation was used to avoid overfitting. Findings were interpreted in the context of a large, prospective pregnancy cohort study utilizing a two-stage approach to case identification. Under initial cutpoints, sensitivity ranged from 0.63 to 0.92 and specificity from 0.35 to 0.70. Cutpoints giving equal weight to sensitivity and specificity resulted in sensitivity estimates ranging from 0.45 to 0.83 and specificity ranging from 0.49 to 0.86. Several strategies were well-suited for application as a second-stage case-confirmation. These included the STAT-E alone and the parallel administration of both the E-VAS and the ASI. Use of more streamlined methods of case-confirmation in large-scale prospective cohort epidemiologic investigations of ASD risk factors appears feasible.

Evidence from the Autism Transitions Research Project (2017-2022): Capstone review and services research recommendations / Anne M. ROUX in Autism Research, 16-3 (March 2023)  

Public ISBD [article]  inAutism Research > 16-3 (March 2023) . - p.480-496 Titre : Evidence from the Autism Transitions Research Project (2017-2022): Capstone review and services research recommendations Type de document : Texte imprimé et/ou numérique Auteurs : Anne M.

SHATTUCK, Auteur Article en page(s) : p.480-496 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Few funding sources have explicitly supported systems-wide research to identify mechanisms for improving access, service delivery, outcomes and wellbeing for autistic transition-age youth and young adults. We aimed to integrate findings from research produced through a five-year federal Autism Transition Research Project (ATRP) cooperative agreement. This capstone review sought to: (1) map the body of scientific evidence that emerged from this federal award, and (2) identify remaining evidence gaps to inform future autism transition services research. We used scoping review methods to assess 31 ATRP-funded published scientific studies. We charted study characteristics, topical domains, socio-ecological levels of variables, focus on equity, and inclusion of autistic participants. We evaluated how these topics were addressed across studies to identify continued gaps in the evidence base. Compared to prior published reviews and research agendas, we found improvements in characterization of study participants, broader examination of socio-ecological correlates, and examination of multiple outcome domains. However, we also identified continued deficits in inclusion of autistic study participants, use of multisectoral data, and research with a strong focus on equity. Our recommended priorities for autism transition services research to facilitate healthy life outcomes and wellbeing included: continued analysis of population-level data and improved data infrastructure; development of service delivery methods and interventions that target marginalized groups; expanded research to inform improvements in the performance and coordination of complex service ecosystems that interface with autistic youth; and bolstering the roles of autistic research participants.
